What the gurus are saying

The tranexamic acid derivative in this serum earns consistent praise for fading dark spots and discoloration, especially when applied over weeks rather than days, and it sits gently alongside retinoids and vitamin C without irritation. Most gurus call it a solid, affordable starting point for mild pigmentation, though one notes that stronger prescription or professional treatments exist if this doesn't deliver after several months of use. One reviewer's skin rejects niacinamide, so patch-testing matters if you are sensitive to that ingredient.

DEBUNKING 7 Skincare Myths Destroying Your Skin| Dr Vanita Rattan | Skin of colour
"I like the discoloration serum from Good Molecules. It's a very good product, a cocktail serum that I would recommend for a skin of color family. [...] It has 10 tyrosinase inhibitors in it. [...] I made it for my skin because there was no middle ground between buying something off the shelf and then going in for professional grade treatment which can cost $500 to $1,000 plus. It costs $98 and you could do it for a good six to eight months to see if we can treat it, if it's gone. [...] If it doesn't work for you, there really is nothing stronger on the market. But please, this is not first line. Do not buy this first. Buy a retinoid first and buy the discoloration serum first. This is not your first time treatment. It's just if nothing else works."
Best & Worst Dark Mark Serums
"Good Molecules Discoloration Serum, 2% tranexamic acid, 4% niacinamide. That is an absolute bargain. [...] That is definitely the one to start with. [...] I would probably start with the Good Molecules discoloration serum and see how you get on with that one first because that is just by far the best buy."
Best and Worst Dark Mark Serums for Skin of colour 2024
"This is $47, so actually quite reasonable. [...] The third ingredient is glycerin, and it comes out a bit milky. The fourth ingredient is niacinamide, then they put in Calcium Tranexamate Melate, which is a derivative of tranexamic acid. It is a naif safe product and it's a good first line, however it is a little bit expensive for what's in here. In fact, you can buy your tranexamic acid plus niacinamide from The Inkey List for a fraction of the price."

"This is Good Molecules' discoloration serum, and it's only 12 bucks, that's drugstore price. It has 4% niacinamide plus a tranexamic acid transporter in there to help deeply transport that niacinamide into the skin."

BEST DEALS ON THE LAST DAY OF AMAZON PRIME DAY
"I think it's a good option, especially at the price point, like $12. But I wasn't overly impressed. Even though it's a good combination of ingredients, I wasn't overly impressed with the performance over time with this product, even though it is a good starter product for dark spots. [...] If you haven't tried any dark spot product and you're looking to start a dark spot product, I think this is a good starter product. But I think there are better, more comprehensive solutions that are currently out there."

"Going to get the Good Molecules Discoloration Correcting Serum and that's 1 oz so you're going to get something that's going to help exfoliate the skin and then something that's going to help with dark spots and discoloration. Remember what I said before, a lot of these over the counter treatments they're for fresher dark spots, [...] but people love Good Molecules. [...] I think there's a post on the Community page where people chimed in on their thoughts on the Good Molecules products. [...] People seem to love it and $26 set sounds good to me."

THESE SERUMS WILL CHANGE YOUR SKIN - Best Skincare Picks 2023
"Specifically for targeting dark spots and discoloration, there have been some recent studies that show the form of tranexamic acid in here, the derivative actually finds it easier to get into the skin to where it needs to be for those results, so you might actually get enhanced results from this product. [...] After just a couple of weeks of using it, I was like wow, I can actually notice the difference. It's super affordable but actually delivers, packs a punch, and really delivers. This I think is a skin-changing, game-changing, amazingly affordable serum that I would recommend time and time again."
TOP 5 HYPERPIGMENTATION SERUMS 2023 - Glowing Skin Guaranteed
"The Good Molecules Discoloration Correcting Serum is really gentle, so you can use it alongside all your other active ingredients from your retinoids to your vitamin C's, it's all compatible with it, so it's a really easy product to just slot straight into your skincare routine. [...] I still absolutely love it. It has some tranexamic acid derivative which is really gentle alongside some other brightening agents. [...] You kind of have to invest in this product, you get long-term payoff but maybe you're not going to get those quick wins, so if you're impatient these might not be for you. But honestly, if you've got sensitive skin this won't irritate it at all and you'll get some really great results in the long term. It's also nice, rich and creamy, and it applies really well onto the skin. These have a little bit of hydration too, which is nice because a lot of hyperpigmentation serums [...] can be a little stripping and drying on the skin. Not with this, it actually adds back to the hydration."

"This is the discoloration correction serum and this is fantastic if you ever get like a blemish or a little bit of pigmentation spot you don't have to hate yourself for it, you don't have to worry about it, but you have an option. This is from Good Molecules, they're made here in San Francisco. It's so inexpensive, just $15. This is actually a new active for you to try in your routine: tranexamic acid, or TXA, which is actually used in emergency medicine if someone comes in with a gunshot wound or major hemorrhaging, they get tranexamic acid, but it actually works as a discoloration corrector as well. The packaging is really nice, so pretty. It's inexpensive but so effective."

What The Industry Won’t Tell You About Product Recalls & Reformulations
"This serum is meant to help with dark spots and pigmentation and even out skin tone, and it works well. The new version has increased the active ingredient, cetyl tranexamate mesylate, by 50 percent, from 2 percent to 3 percent, which they're saying has more penetration and works better on skin without increasing irritation. They removed butylene glycol and phenoxyethanol, which can be irritating for some people. The new formula goes on smoother and absorbs better. It's much more milky and creamy and pearlescent, and it soaks into the skin and absorbs better than the old one. It goes in almost immediately and dries down without any tacky or greasy feeling. The new formula works a little bit faster than the old one, and those who have used it love it a lot better. I appreciated that they were able to find ways to make it better and to make the packaging less environmentally taxing."
15 Products I Would Drive 1000 Miles For
"If you are struggling with hyperpigmentation, if you get dark marks after acne, if you do have a little bit of sun damage, this is it for you. This has tetraceutic TX vector which is a form of tranexamic acid that is supposed to penetrate deeper into the skin. It also has niacinamide which stops pigmentation from spreading. Niacinamide doesn't stop your skin from actually creating pigment, it allows it to be created and then it just says no, you stay right here and don't spread to the keratinocytes over there. This is such a great serum especially if you struggle with hyperpigmentation and acne."
The Keys To Hyperpigmentation? Skincare Routine That Actually Works | Morning & Nighttime
"The Discoloration Correcting Serum from Good Molecules contains tetracyclic TX Vector, which is a patented form of tranexamic acid that is supposed to penetrate deeper and be a little bit less irritating and more stable. What I also love about this is that it contains niacinamide. For evening, this is a fantastic formula if you want something that is gentle on the skin and non-offensive. There aren't any majorly harsh actives in here that could cause the skin to do a 180, and you're looking for something that has those benefits in a nice night serum. This is an inexpensive and affordable but effective option."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.
